YAGO2: A Spatially and Temporally Enhanced Knowledge Base from Wikipedia
YAGO as Linked Open Data
YAGO2 is part of the linked data cloud. We are linked directly to DBpedia. You can download these links.
- sameAs-links between the individuals of DBpedia and YAGO2: download N3 (27Mb)
- sameAs-links between the classes of YAGO2 and the YAGO-based classes of DBpedia: download N3 (4Mb)
- subClassOf-links between the classes of YAGO2 and the manual ontology classes of DBpedia: download as TSV (with precision), download as RDF/TTL (cut at 60% precision). These links have been computed automatically by the PARIS project and are not 100% accurate.
- subPropertyOf-links between the relations of YAGO2 and the manual ontology properties of DBpedia: download as TSV (with precision), download as RDF/TTL (cut at 40% precision). These links have been computed automatically by the PARIS project. They are not perfect, but of very reasonable quality.
The namespace of YAGO is http://yago-knowledge.org/resource/.
YAGO Applications
YAGO is being used in numerous projects around the globe:
- Ontology Construction projects
- The SUMO Ontology is a highly axiomized manually created ontology.
SUMO and YAGO have been merged in the YAGO-SUMO project.
- DBpedia is a community effort to extract structured information from Wikipedia.
YAGO contributes a taxomic backbone to DBpedia.
- The Linking Open Data Initiative aims to
interlink existing ontologies through Web services.
By help from our friends at DBpedia, YAGO is part of this initiative.
- The UMBEL ontology aims to provide a lightweight structure of subject concepts as a reference to what Web content or data "is about".
YAGO contributes the entities to UMBEL.
- Freebase is a community-based approach to ontologies.
YAGO technology has been exported to Freebase.
- Cyc is a commercial ontology project
We are planning to explore joint possibilities.
- Other Projects of which we know
- The Jeopardy contestant WATSON uses YAGO (see this article)
- The SPASS YAGO reasoner can perform automated reasoning on YAGO.
- Our YAGO-NAGA project addresses a wide range of key challenges in the area of semantic information processing.
See links on the left for the works in this project.
- The ESTER search engine combines full text search with semantic search on YAGO.
- The ObjectRunner system uses YAGO to extract information from Web tables.
